[114.] Show what is wrong in the following:—
8-8 = 2-2, dividing both these equals by 2-2 the result must be equal; 8-8 divided by 2-2 = 4, and 2-2 divided by 2-2 = 1, therefore, since the quotients of equals divided by equals must be equal, 4 must be equal to 1.
“GLAD TIDINGS.”
Many will be surprised to hear that there is Scriptural authority for advertising. Advertising not only has Scriptural authority, but it is of very respectable antiquity as well. If you will look in Numbers XXIV., 14, you will find Balaam saying “Come now, and I will advertise,” and Boaz says in Ruth IV., 4, “And I thought to advertise.”
OPTICAL ILLUSIONS.
Illusions of the Eye are numberless, and afford a wide field for experiment. Some people are left-eyed, others right-eyed, and very few use both eyes equally. It is impossible to tell how far they really do deceive us unless they have been tested in the proper manner. For instance, if you ask anyone to what height a bell-topper would reach if placed on the floor against the wall, nine times out of ten the height guessed will be half as much again as the real height of the hat. Everyone seems to over-estimate the proper height.
